Arduino is a widely used open-source hardware and software development platform that allows users to create custom projects with ease. With Arduino, you can work on the basics of code and gain better control over your engineering and programming workflow.
In this blog post, we’ll explore the basic types of control statements among other important topics related to coding with Arduinos! From if/else and switch cases to execution flow order, we will cover what every programmer needs to know about these key components when using an Arduino. So let’s get right into it – grab your Arduinos and let’s explore some control statements!

Control statements in Arduino
Control statements are an important part of programming in any language, including Arduino. They allow you to control the flow of your program by deciding which lines of code should run depending on certain conditions. This allows you to create more complex programs with logical decisions built into them.
In Arduino, there are three main types of control statements: if/else, switch case, and while loops. The if/else statement is used to check one or more conditions and then perform a task based on whether those conditions are true or false. The switch case statement is similar to the if/else statement but it can be used for multiple conditions instead of just one or two. Lastly, the while loop will continuously execute its contents until a certain condition is met.
Using control statements can help you make your Arduino programs more efficient, as it allows you to avoid running unnecessary code or repeating the same task multiple times. They also allow for greater flexibility when programming complex tasks and can help simplify the structure of your programs.
Control statements are an essential part of programming in Arduino, so it’s important to understand how they work and how to use them correctly. With a bit of practice and some trial and error, you’ll soon be writing sophisticated sketches with ease!
What are the different types of control statements in Arduino?
In Arduino, control statements are used to check for a certain condition and execute a block of code depending on its result. The different types of control statements available in Arduino are the if statement, the if-else statement, switch-case statements, and the conditional operator.
There are different types of control statements which are described in detail one by one:
The ‘if’ statement can be used to evaluate an expression and execute a set of instructions when it evaluates to true. It is usually used with relational operators such as greater than (>), less than (<), and equal to (==). For example, you could use an if statement to turn on an LED light when the temperature is above 20 degrees Celsius.
The ‘if-else’ statement works similarly, but it provides two possible outcomes based on the expression result. If the expression is true, then the set of instructions in the ‘if’ part will be executed; otherwise, the instructions in the ‘else’ part will be executed. In other words, with an if-else statement, you can check for two different conditions and execute a specific code block depending on which one evaluates to true.
The switch-case statements provide more flexibility than the if statements as they offer multiple possible outcomes based on different expressions. It consists of a switch keyword followed by one or more case statements that evaluate different expressions. Depending on which expression evaluates to true, its corresponding instructions will be executed. Switch-case statements are usually used when there are more than two possible outcomes for an expression evaluation.
Finally, the conditional operator is used to evaluate an expression and assign a value to a variable depending on the result. It consists of three operands – a Boolean expression, a value if the expression evaluates to true, and another value if it evaluates to false. For example, you could use it to assign ‘high’ or ‘low’ values to a variable based on whether an LED is turned on or off.
In summary, control statements are an essential part of programming in Arduino as they allow us to check for different conditions and execute specific instructions accordingly. Control statements are employed to organize the execution of Arduino code. Depending on specific circumstances, it will regulate how the statements are executed. The control statements in Arduino are described in this article with the use of examples.
